--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This sounds like it is still picking up the wrong libstdc++ really.

Can you disassemble (objdump -dr) ~/usr/lib64/libstdc++.so.6 to see which
vsnprintf is used there?

Also can you set LD_LIBRARY_PATH to ~/usr/lib64/ rather than using LD_PRELO=
AD
and see if that works.
The other thing to do use LD_DEBUG to figure out which libstdc++ is being u=
sed
really.=
